  • At least one washing program for carrying out or controlling a washing process also called a washing cycle, for washing dishes, in particular for washing dishes, is stored in the control device.
  • several washing programs are provided, one of which can be selected and started by the operator. This makes it possible to adapt the course of a wash cycle, in particular to the load quantity, to the load type, to the degree of contamination of the washware and / or to the desired duration of the wash cycle.
  • the respective stored wash program can preferably be designed such that the wash cycle controlled by the wash program in each case a plurality of partial wash cycles, in particular at least one pre-wash cycle for pre-cleaning washware, at least one cleaning cycle for thorough cleaning of washware, at least one intermediate wash cycle for removing soiled washing liquid from the washware, comprises at least one rinse cycle to avoid stains on the wash ware and / or to prepare a drying step or drying cycle, and / or at least one drying cycle to dry the wash ware, in the chronological order specified above.
  • Pre-rinse, cleaning, intermediate rinse and rinse are referred to as water-carrying partial rinses, since the items to be washed that have been introduced into the rinsing chamber are treated with a rinsing liquid during their execution.
  • rinsing liquid is generally not intended during the drying cycle.
  • the treatment of the items to be washed with washing liquid can be carried out in a substantially closed washing chamber, in particular a washing container, of the dishwasher respectively.
  • an inlet valve can be assigned to the rinsing chamber, which makes it possible to pour rinsing liquid into the rinsing chamber.
  • a circulating pump for circulating a washing liquid can be assigned to the washing chamber, which enables the washing liquid filled into the washing chamber, e.g. B. from a collecting device for rinsing liquid, and apply to the items to be washed via a spray system assigned to the rinsing chamber.
  • a rinsing liquid is understood here in particular to be a liquid which is intended to be applied to the items to be washed in order to clean them and / or to treat them in another way.
  • the washing liquid can also be provided for heating the items to be washed, which is possible, for example, during a rinse step to prepare a subsequent drying cycle in which the drying is based at least in part on the fact that the washing liquid adhering to the items to be washed evaporates due to the heat stored in the items to be washed.
  • the rinsing liquid entering the rinsing chamber via the inlet valve is usually fresh water.
  • the washing liquid in the washing chamber can be enriched with cleaning agents, cleaning aids such as rinse aid and / or with dirt that has been detached from the items being washed.
  • cleaning aids such as rinse aid and / or with dirt that has been detached from the items being washed.
  • already enriched water is filled into the rinsing chamber as rinsing liquid via the inlet valve.
  • the washing chamber is assigned a drain pump for pumping out washing liquid.
  • the drain pump makes it possible to dispose of washing liquid that is no longer required, in particular heavily soiled, in the washing chamber, for B. from the collecting device for rinsing liquid and z. B. to be delivered to a waste water disposal facility installed on the building.
  • the drain pump is controlled and / or regulated during the execution of a wash cycle by the control device of the dishwasher depending on the wash program selected in each case. It can in particular be provided that the rinsing liquid used in each case is pumped out at the end of a water-carrying partial rinse cycle in order to be carried out in the subsequent partial rinse cycle Pour as clean or less dirty washing liquid as possible into the washing chamber and use it to clean the dishes.
  • the drain pump is usually designed as a centrifugal pump, in particular as a radial pump, as a semi-radial pump or as an axial pump.
  • a centrifugal pump is a turbomachine in which the respective liquid is conveyed using the centrifugal force by means of a rotating conveying element.
  • the design of the drain pump as a centrifugal pump leads, better or differently than, for example, in the case of a design as a piston pump, to the function of the drain pump being ensured even when the rinsing liquid to be pumped out is heavily contaminated.
  • the amount of washing-up liquid in the dishwasher initially decreases substantially linearly over the course of time, with the speed of rotation remaining the same. If a certain residual amount of rinsing liquid is undershot, however, such an amount of air enters the drain pump that the pressure for delivering rinsing liquid breaks down and consequently no more rinsing liquid is delivered. In this way, a residual amount of washing liquid that cannot be pumped off during continuous operation of the drain pump remains in the dishwasher.
  • the first of the pumping phases is intended for pumping out at least 80%, preferably at least 90%, particularly preferably at least 95%, of the total amount of the rinsing liquid to be pumped out. This makes it possible to effectively reduce the residual amount of washing liquid remaining in the dishwasher by means of the subsequent pump-down phases.
  • the first pumping-out phase of the pumping-out phases is provided for pumping out an amount of flushing liquid that can be pumped out during continuous operation of the drain pump. In this way it is possible to reduce the remaining amount of washing-up liquid in the dishwasher particularly effectively by means of the subsequent pump-down phases.
  • a monitoring device for monitoring a flushing liquid flow conveyed by the drain pump, the first pumping-off phase of the pumping-off phases being terminated if the monitoring device detects that the flushing liquid flow has fallen below a minimum value. If a minimum value for the amount of rinsing liquid pumped out per unit of time, that is to say for the flow of rinsing liquid pumped, is undershot, this indicates that the amount of rinsing liquid that can be pumped out during continuous operation of the drain pump has essentially been pumped out.
  • the termination of the first pump-down phase is initiated on the basis of this criterion, it can be ensured that, on the one hand, the amount of flushing liquid that can be pumped out in the first pumping step is at least essentially achieved, and that, on the other hand, an unnecessary duration of the first pump-down phase is avoided.
  • the drain pump has an electric motor, the monitoring unit being designed to monitor at least one electrical operating parameter of the electric motor.
  • the monitoring unit being designed to monitor at least one electrical operating parameter of the electric motor. This is based on the knowledge that electrical operating parameters of electric motors of drain pumps change characteristically depending on the flow of rinsing liquid. This applies, for example, to a drain pump operated with a fixed voltage for its current or power consumption. At a given speed, the power consumption of an air-suction drain pump is generally significantly lower than the power consumption of an exclusively detergent-drain drain pump.
  • Such a monitoring unit is simply constructed. This is particularly true when compared to monitoring devices that have a special flow meter, such as an impeller meter.
  • a termination of the first drain phase of the drain phases is provided if, after a predetermined period of time, the monitoring device does not detect that the flushing liquid flow has fallen below the minimum value. In this way it can be prevented that in the event of a malfunction of the monitoring device, the first pump-down phase is continued indefinitely.
  • At least one of the drain phases following the first drain phase and / or at least one of the breaks is terminated in a time-controlled manner.
  • the intended pumping sequence can be implemented in a simple manner, in particular without additional sensors.
  • At least one of the pauses has a duration of at least 1 second, preferably at least 2 seconds, particularly preferably at least 4 seconds, and / or at most 24 seconds, preferably at most 12 seconds, particularly preferably at most 7 Seconds on.
  • the specified minimum values for the duration of the breaks are normally sufficient for the rinsing fluid swirled up in the previous drain phase to come to a rest position in the drain pump during the respective break, in which at least a brief pressure build-up is possible by starting the drain pump.
  • the specified maximum values also ensure that the entire pumping sequence does not take longer than necessary.
  • At least one of the drain phases following the first drain phase has a duration of at least 1 second, preferably of at least 2 seconds, particularly preferably of at least 4 seconds, and / or of at most 32 seconds, preferably of at most 16 seconds, particularly preferably of at most 8 seconds.
  • the maximum amount of flushing liquid that can additionally be pumped out when the drain pump starts up can generally be achieved in each of the subsequent drain phases.
  • the specified maximum values also ensure that the entire pumping sequence does not take longer than necessary.
  • At least one washing program can be selected for carrying out a washing cycle, in which the pumping-out sequence is provided at the end of a partial washing cycle provided as an intermediate washing cycle.
  • a reduction in the amount of washing liquid not pumped out leads to a reduction in carryover of cleaning agent and / or dirt into the last washing liquid of a washing cycle, which is generally the washing liquid of a partial washing cycle designed as a rinse cycle.
  • the gloss effect on the items being washed can be increased particularly effectively.
  • At least one wash program can be selected for carrying out a wash cycle, in which the pumping sequence is provided at the end of a partial wash cycle provided as a cleaning cycle.
  • the pumping sequence is provided at the end of a partial wash cycle provided as a cleaning cycle.
  • carryover of detergent and / or dirt into an intermediate rinse cycle can generally be prevented, so that the rinsing liquid contains less detergent and / or dirt in this intermediate rinse cycle.
  • a further carry-over of cleaning agent and / or dirt into the last rinsing liquid of a wash cycle can be further minimized and the gloss effect on the washed items can be increased.
  • At least one rinsing program can be selected for carrying out a rinsing cycle, in which, at the end of a partial rinsing cycle provided as a pre-rinsing cycle, a short pump-down sequence is provided which comprises fewer pump-down phases than the pump-down sequence.
  • a short pump-down sequence At the end of a normal pre-wash cycle, a larger amount of dirt generally adheres to the dishes. Since this is normally replaced in the subsequent cleaning cycle, any carryover of dirt from the pre-rinsing cycle into the cleaning cycle is not significant. Therefore, at the end of a pre-rinse cycle, a short pump-down sequence can be used to drain, which accelerates the execution of the rinse cycle.
  • At least one wash program can be selected for carrying out a wash cycle, in which a short pump-down sequence is provided at the end of a partial wash cycle provided as a rinse cycle, which comprises fewer pump-down phases than the pump-down sequence.
  • a short pump-down sequence is provided at the end of a partial wash cycle provided as a rinse cycle, which comprises fewer pump-down phases than the pump-down sequence.
  • the rinsing liquid used is essentially free of cleaning agents and / or dirt. Therefore, carryover of cleaning agents and / or dirt into a later rinse cycle is at most possible to a small extent and not disruptive. Therefore, at the end of a rinse aid cycle without any disadvantage a short pump down sequence are pumped out, which further accelerates the execution of the rinse cycle.
  • the drain pump comprises a brushless electric motor, preferably a brushless permanent magnet motor.
  • the brushless electric motor can in particular be designed as a brushless DC motor, also called a BLDC motor, as a brushless AC motor, also called a BLAC motor, or as a synchronous motor.
  • the rotor of the motor can have at least one permanent magnet, whereas the stator has several electromagnets.
  • the electromagnets are commutated via control electronics.
  • a defined starting of the motor from standstill can be achieved in this way, so that the amount of flushing liquid that can additionally be pumped out in the pumping phases following the first pumping phase can be maximized.
  • a circulation pump for supplying washware with washing liquid is switched off for the entire duration of the pumping sequence. This prevents rinsing liquid from being distributed by the circulation pump in the dishwasher during the pumping sequence, so that it cannot be pumped out by means of the drain pump.
  • a wash program is selected at which at least one pump-down sequence is carried out automatically, which comprises at least three pump-down phases, for the duration of which the drain pump is switched on, with a pause being provided between successive pump-down phases of the at least three pump-down phases, for the duration of which the drain pump is switched off.

  • FIG 3 shows an exemplary rinse cycle SG of the dishwasher 1 according to the invention, which brings about a special gloss effect on the cleaned items by means of less carryover of dirt and / or cleaning agent into the last rinsing liquid S used.
  • the rinse cycle SG comprises several partial rinse cycles, namely in the following chronological order a pre-rinse cycle VG for pre-cleaning washware, a cleaning cycle RG for thorough cleaning of washware, an intermediate rinse cycle ZG for removing dirty washing liquid S from the washware, a rinse cycle KG to avoid stains on the washware and a drying cycle TG for drying the wash ware.
  • some of the partial rinse cycles mentioned for example the pre-rinse cycle VG, could be dispensed with. Additional partial rinse cycles, for example a second intermediate rinse cycle, could also be provided.
  • a filling sequence F 1 for filling the washing chamber 7 with washing liquid S is carried out.
  • the filling valve 18 is opened temporarily in the exemplary embodiment.
  • a circulation sequence U 1 is carried out, in which the washware is supplied with circulated washing liquid S.
  • the circulation pump 31 is switched on at least temporarily during the circulation sequence U 1 .
  • a short pumping sequence KA 1 is carried out, during which at least a substantial part of the washing liquid S, which is located in the washing chamber 7 and is now contaminated, is delivered to the waste water pipe AR by means of the drain pump 31, for example.
  • the execution of the short pumping sequence KA 1 at the end of the pre-rinse cycle VG can accelerate the execution of the rinse cycle, although increased carryover of dirt into the subsequent cleaning cycle RG by rinsing liquid that has not been pumped out is possible.
  • this does not cause any major problems, since at the end of the pre-wash cycle VG there is generally still a larger amount of dirt adhering to the wash ware, which is normally detached in the subsequent cleaning cycle RG and pollutes the washing liquid S used there, so that possible carryover of dirt through not drained rinsing liquid from the pre-rinse cycle into the cleaning cycle is of no importance.
  • further rinsing liquid S is introduced into the rinsing chamber 7 by means of a further filling sequence F 2 and circulated in a further circulation sequence U 2 .
  • the cleaning effect of the cleaning cycle is increased by heating the rinsing liquid S in a heating phase H 2, for example by means of the heating device 24 and / or by means of the waste heat from a regeneration phase of the sorption drying device 39.
  • cleaning agent RZ is added in the cleaning cycle RG, for example via the metering device 28. In this way, the dirt adhering to the items to be washed can be almost completely removed in the cleaning cycle RG.
  • a pumping sequence A 2 which is also described in more detail below, is carried out at the end, which is characterized in that a non-pumpable residual amount of rinsing liquid S is reduced compared to the short pumping sequence KA 1 . In this way, carryover of dirt and / or cleaning agent into the intermediate rinse cycle ZG carried out afterwards is reduced.
  • the intermediate rinse cycle ZG comprises a further filling sequence F 3 for filling the rinsing chamber 7 with rinsing liquid S and a further circulation sequence U 3 , which essentially serves to rinse off residues of the rinsing liquid S of the cleaning cycle RG from the items to be washed.
  • the disruptive residues can be removed particularly well, since, due to the almost complete pumping out of the washing liquid S of the cleaning cycle R in the intermediate washing cycle ZG, a particularly clean washing liquid is available.
  • the rinsing liquid S of the intermediate rinsing cycle ZG also absorbs only a little dirt and / or cleaning agent during the intermediate rinsing cycle, so that the rinsing liquid S at the end of the intermediate rinsing cycle ZG is considerably cleaner than would be the case if a short pumping sequence was carried out at the end of the cleaning cycle RG would have been.
  • a pumping sequence KA 3 is now carried out, which is also characterized in that a non-pumpable residual amount of washing liquid S is reduced compared to the short pumping sequence KA 1 . In this way, carryover of dirt and / or cleaning agent into the rinse aid KG from the already relatively clean rinsing liquid S of the intermediate rinse cycle Z is further reduced.
  • a further filling sequence F 3 is used to circulate rinsing liquid S in a circulation sequence U 4 .
  • the addition ZK of rinse aid is provided, for example via the metering device 29, in order to reduce the surface tension of the washing liquid S.
  • the washing liquid S runs off the items to be washed better, which serves to prevent stains on the items to be washed in a known manner.
  • the last rinsing liquid S of the rinse cycle SG in the exemplary embodiment the rinsing liquid of the rinse cycle KG, contains significantly less dirt and / or cleaning agent, so that the formation of stains on the cleaned items continues is reduced.
  • the rinsing liquid of the rinse aid KG can be carried out easily by means of a further short pumping sequence KA 4 , since due to its low content of dirt and / or cleaning agent, it is generally not possible to carry the dirt and / or cleaning agent into a later rinse cycle SG.
  • the items to be washed are dried during a drying sequence T 5 in the exemplary embodiment by means of warm, dry air from the sorption drying device 39.
  • the rinsing liquid S used there could be heated during the final rinse cycle KG by means of a heating phase not provided in the exemplary embodiment.
  • the circulation pump 22 is switched off for the entire duration of the pumping sequences A 2 and A 3 and the short pumping sequences KA 1 and KA 4 . This prevents rinsing liquid S from being distributed by the circulating pump 22 in the dishwasher 1 during the pumping-down sequences A 2 and A 3 and the short pumping-down sequences KA 1 and KA 4 , so that it cannot be pumped out by means of the drain pump 31.
  • Figure 4 shows a schematic representation of a pumping sequence A of the dishwasher of the invention Figures 1 and 2nd which the in Figure 3 Pumping sequences shown A 2 and A 3 corresponds.
  • the upper part of the diagram shows the amount M in% of the amount of rinsing liquid S still in the rinsing chamber 7 based on the amount present at the beginning of the pumping sequence A over time t.
  • This set M can also be referred to as the relative set M.
  • the operating state Z31 of the drain pump 31 is shown in a lower part of the diagram.
  • the operating state “1” means that the drain pump 31 is switched on, and the operating state "0" means that the drain pump 31 is switched off.
  • the pumping sequence A comprises three pumping phases AP 1 , AP 2 and AP 3 , during which the drain pump 31 is switched on continuously. Furthermore, breaks P 1 and P 2 are provided during which the circulation pump 31 is switched off continuously.
  • the draining phase AP 1 is separated from its neighboring draining phase AP 2 by a break P 1, and this in turn is separated from its neighboring draining phase AP 3 by a break P 2 .
  • the drain pump 31 can in particular be designed as an electric centrifugal pump, for example as a radial pump, as a semi-radial pump or as an axial pump.
  • the execution of the drain pump 31 as a centrifugal pump leads, better or differently than, for example, in a version as a piston pump, to the function of the drain pump being ensured even when the rinsing liquid to be pumped is heavily contaminated.
  • the drain pump 31, which is designed as a centrifugal pump, is now switched on at the beginning of the first pumping-down phase AP 1 , the relative amount M of the washing liquid S in the dishwasher 1 initially decreases substantially linearly over the course of time, with the speed of the drain pump 31 remaining constant. If a certain residual amount RMD of flushing liquid S is undershot at time T1, however, such an amount of air enters the circulation pump 31 that the pressure for conveying flushing liquid S breaks down and consequently no flushing liquid S is conveyed anymore.
  • This condition can be monitored 38 can be determined, for example, by monitoring an electrical parameter of the drain pump 31, whereupon the first drain phase AP 1 can be ended.
  • the first drain phase remains in the dishwasher at the end of a non abpumpbare in continuous operation of the drain pump 31 remaining quantity RMD of rinsing liquid S.
  • this ensures that during the first drain phase AP 1, the abpumpbare in continuous operation of the circulation pump 31 amount AMD of rinsing liquid S is actually pumped out. In this way, it is possible to reduce the residual amount RM of washing liquid S remaining in the dishwasher 1 particularly effectively by means of the subsequent pumping phases AP 2 , AP 3 .
  • the breaks P 1 and P 2 can last for at least 1 second, preferably at least 2 seconds, particularly preferably at least 4 seconds, and / or at most 24 seconds, preferably at most 12 seconds, particularly preferably at most 7 seconds, exhibit.
  • the specified minimum values for the duration of the pauses P 1 and P 2 are normally sufficient for the rinsing liquid S whirled up in the previous pump-down phase AP 1 or AP 2 in the drain pump 31 during the respective pause P 1 or P 2 in reaches a rest position, in which at least a brief pressure build-up is possible by starting the drain pump 31.
  • the specified maximum values further ensure that the entire pumping sequence A does not take longer than necessary.
  • the pump-down phases AP 2 and AP 3 following the first pump-down phase AP 1 preferably have a duration of at least 1 second, preferably of at least 2 seconds, particularly preferably of at least 4 seconds, and / or of at most 32 seconds, preferably of at most 16 seconds, particularly preferably of at most 8 seconds.
  • the amount of flushing liquid S additionally pumpable when the drain pump 31 starts can be achieved in each of the subsequent drain phases AP 2 and AP 3 .
  • the specified maximum values further ensure that the entire pumping sequence A does not take longer than necessary.
  • FIG. 5 shows a schematic representation of a short pumping sequence KA of the dishwasher 1 according to the invention Figures 1 and 2nd .
  • the short pumping sequence KA essentially differs from the pumping sequence A in that fewer pumping phases, for example only one pumping phase AP 1, are provided. This results in a changed relative amount M 'of washing liquid in the washing chamber 7 over time, the amount RM' present at the end of the short pumping sequence KA being greater than the amount RM at the end of the pumping sequence A, which, as already stated, at the end of the Pre-wash cycle VG and at the end of the rinse cycle can be tolerated.
  • this has the advantage that the time required for the short pumping sequence KA can be significantly reduced compared to the pumping sequence A.
  • the invention has the effect that cleaned glasses and cutlery are better free of stains.
  • the effect is preferably achieved by combining a drying process with a sorption system, for example with a zeolite system, or a conventional drying process with the special pumping process shown, which reduces carryover of dirt and or cleaning agents.
  • a second intermediate rinse with a pumping sequence according to the invention is carried out after the first intermediate rinse and the subsequent rinse.
